Abstract
A disposable tape tab closure system for a diaper or a like article is provided with at least a fastening tape tab portion and a release tape tab portion, the fastening tape tab portion having an adhesive surface opposite the release surface face of a release tab portion the two tabs forming a laminate attached to one face of a disposable garment. The fastening tape tab portion attached to a second face of the disposable garment by a pressure-sensitive adhesive hinge tape with no adhesive bond between the fastening tape tab and the release tape tab.
Claims
exact text as granted — not AI-modifiedI claim:
1. A disposable garment pressure-sensitive adhesive closure tape tab system comprising a closure tab laminate, comprised of a fastening tape tab portion having a substrate with a first and second face, and a release tab portion having a substrate with a first and second face, and a hinge tape having a substrate with a first face and a second face, the release tab portion substrate first face having a release layer with no release layer on said second face, said fastening tape tab portion first face having an adhesive layer, said two tab portions first faces are releasably attached to each other, such that the fastening tape tab portion adhesive layer does not form a permanent adhesive bond to said release tab with said fastening tape tab portion first face in face-to-face contact with said release tape tab portion first face, the release tab portion second face is attached to a first face of a disposable garment adjacent an edge thereof, said hinge tape first face coated with a pressure-sensitive adhesive layer, a first end of the hinge tape first face permanently adhesively attached to said fastening tape tab portion second face and a second end of said hinge tape first face permanently adhesively attached to said disposable garment second face adjacent said edge and opposite said release tab portion thereby permanently attaching the fastening tape tab to the disposable garment wherein the fastening tape tab second face has no adhesive layer other than that provided by the adhesive layer on the first end of the hinge tape second face.
2. The closure tape tab system of claim 1 wherein said fastening tape tab portion second face comprises a release layer and said release tab portion second face has an adhesive layer forming a release tape tab.
3. The tape closure system of claim 2 wherein said release tape tab portion and said fastening tape tab portion are coextensive, with the entire fastening tape tab releasable from the release tape tab portion.
4. The tape closure system of claim 3 wherein said fastening tape tab portion adhesive layer is less aggressive than said hinge tape adhesive layer.
5. The tape closure system of claim 1 wherein said release tab portion first face has a structured surface and the fastening tape tab portion first face pressure-sensitive adhesive is in mating contact with said structured surface forming a structured pressure-sensitive adhesive layer.
6. The tape closure system of claim 5 wherein said release tab first face structures are at least 25 microns high.
7. The tape closure system of claim 1 wherein said hinge tape backing is an oriented thermoplastic polymer film.
8. The tape closure system of claim 7 wherein said hinge tape backing is 10 to 80 microns thick.
9. The tape closure system of claim 7 wherein said hinge tape adhesive is more aggressive than said fastening tape tab first face adhesive layer and is 15 to 90 percent of the size of the fastening tape tab with at least 1.0 cm of said hinge tape attached to said disposable garment second face.
10. The tape closure system of claim 9 wherein said disposable garment comprises a disposable diaper with said disposable garment first face being a water permeable topsheet layer and said disposable garment second face being a water impermeable backsheet layer.Cited by (0)
